This course provides an introduction to the organization, legal structure, and role of U.S. administrative agencies. Topics include the constitutional foundations of the administrative state, the Administrative Procedure Act, the process of agency rulemaking and adjudication, and the mechanisms of judicial review of agency actions. We will also examine substantive areas such as consumer protection, transportation, and environmental regulation. The course will also address key normative debates surrounding the delegation of legislative authority to agencies, the scope of executive control over agency operations, and the proper extent of judicial oversight. Throughout, we will emphasize what policymakers and advocates need to know when working with or within federal agencies. By the end of the course, students will gain a practical understanding of the legal, policy, and political dynamics that shape the modern U.S. administrative state.
